2021-02-04drivers/intel/fsp2_0: Fix running on x86_64Patrick Rudolph
Add new Kconfig symbols to mark FSP binary as x86_32. Fix the FSP headers and replace void pointers by fixed sized integers depending on the used mode to compile the FSP. This issue has been reported here: https://github.com/intel/FSP/issues/59 This is necessary to run on x86_64, as pointers have different size. Add preprocessor error to warn that x86_64 FSP isn't supported by the current code. Tested on Intel Skylake. FSP-M no longer returns the error "Invalid Parameter".

2021-02-03drivers/aspeed: Fix some issuesPatrick Rudolph
* Use probe_resource instead of find_resource. This prevents a call to die and instead returns NULL. * Handle the case where BAR2 isn't present * Don't hardcode legacy VGA when BAR2 is present. This fixes graphic initialisation when the Aspeed isn't the primary GPU and thus doesn't decode VGA cycles. This makes the coreboot code more similar to the Linux kernel code.

Allow platforms to use the coreboot postcar code instead of calling into FSP-M TempRamExit API. There are several reasons to do this: - Tearing down CAR is easy. - Allows having control over MTRR's and caching in general. - The MTRR's set up in postcar be it by coreboot or FSP-M are overwritten later on during CPU init so it does not matter. - Avoids having to find a CBFS file before cbmem is up (this causes problems with cbfs_mcache) Change-Id: I6cf10c7580f3183bfee1cd3c827901cbcf695db7 Signed-off-by: Arthur Heymans <arthur@aheymans.xyz> Reviewed-on: https://review.coreboot.org/c/coreboot/+/48466 Reviewed-by: Patrick Georgi <pgeorgi@google.com> Reviewed-by: Angel Pons <th3fanbus@gmail.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>

Remove board-specific implementations for google/drallion and google/sarien and select the new Kconfig instead. Test: build/boot google/akemi with RO_VPD region persisted from stock Google firmware, verify system/mainboard serial numbers present via dmidecode.

2021-01-04drivers/vpd: Add VPD region to default FMAP when selectedMatt DeVillier
Currently, use of the VPD driver to read VPD tables from flash requires the use of a custom FMAP with one or more VPD regions. Extend this funtionality to boards using the default FMAP by creating a dedicated VPD region when the driver is selected. Test: build qemu target with CONFIG_VPD selected, verify entry added to build/fmap.fmd.

2020-12-08drivers/i2c/tpm: Unconditionally allow I2C TPM ACPI nodeJes Klinke
DRIVER_I2C_TPM_ACPI is used to enable the "driver" needed for coreboot to present a TPM node in the devicetree. It would usually only do so, if coreboot itself is communicating with the TPM via I2C (I2C_TPM). However, technically, there is no dependency. In order to not show the ACPI option in menuconfig if the board is not using I2C, a dependency was declared in Kconfig. However, the same can be achieved without making it an error to manually declare DRIVER_I2C_TPM_ACPI without I2C_TPM. For Volteer, we have just such a need, since it has two "sub-variants" sharing the same overridetree.cb, one having SPI TPM and another having I2C TPM. The former will have a disabled ACPI node representing the I2C TPM, while its Kconfig is such that coreboot itself does not have I2C TPM support. In order to export even a disabled ACPI node representing the I2C connected TPM, coreboot needs DRIVER_I2C_TPM_ACPI. Hence, that will have to be enabled in a case where coreboot does not have I2C_TPM (for one of the two sub-variants, namely volteer2).

This patch renames cbfs_boot_map_with_leak() and cbfs_boot_load_file() to cbfs_map() and cbfs_load() respectively. This is supposed to be the start of a new, better organized CBFS API where the most common operations have the most simple and straight-forward names. Less commonly used variants of these operations (e.g. cbfs_ro_load() or cbfs_region_load()) can be introduced later. It seems unnecessary to keep carrying around "boot" in the names of most CBFS APIs if the vast majority of accesses go to the boot CBFS (instead, more unusual operations should have longer names that describe how they diverge from the common ones). cbfs_map() is paired with a new cbfs_unmap() to allow callers to cleanly reap mappings when desired. A few new cbfs_unmap() calls are added to generic code where it makes sense, but it seems unnecessary to introduce this everywhere in platform or architecture specific code where the boot medium is known to be memory-mapped anyway. In fact, even for non-memory-mapped platforms, sometimes leaking a mapping to the CBFS cache is a much cleaner solution than jumping through hoops to provide some other storage for some long-lived file object, and it shouldn't be outright forbidden when it makes sense. Additionally, remove the type arguments from these function signatures. The goal is to eventually remove type arguments for lookup from the whole CBFS API. Filenames already uniquely identify CBFS files. The type field is just informational, and there should be APIs to allow callers to check it when desired, but it's not clear what we gain from forcing this as a parameter into every single CBFS access when the vast majority of the time it provides no additional value and is just clutter.

2020-11-26drivers/intel/fsp2_0: introduce possibility of using a full FD binaryMichael Niewöhner
Currently, setting a custom FSP binary is only possible by using split FSP-T/M/S FD files. This change introduces the possibility to pass a combined FD file (the "standard" FSP format). This is done by adding a new boolean Kconfig FSP_FULL_FD, specifying that the FSP is a single FD file instead of split FSP-T/M/S FD files, and making FSP_FD_PATH user-visible when the option is chosen. In this case, the other options for split files get hidden. When the user chooses to use a full FD file instead of the split ones, the FD file gets split during build, just like it is done when selecting the Github FSP repo (FSP_USE_REPO). Test: Supermicro X11SSM-F builds and boots fine with custom FSP FD set.

2020-11-13mrc_cache: Move code for triggering memory training into mrc_cacheShelley Chen
Currently the decision of whether or not to use mrc_cache in recovery mode is made within the individual platforms' drivers (ie: fsp2.0, fsp1.1, etc.). As this is not platform specific, but uses common vboot infrastructure, the code can be unified and moved into mrc_cache. The conditions are as follows: 1. If HAS_RECOVERY_MRC_CACHE, use mrc_cache data (unless retrain switch is true) 2. If !HAS_RECOVERY_MRC_CACHE && VBOOT_STARTS_IN_BOOTBLOCK, this means that memory training will occur after verified boot, meaning that mrc_cache will be filled with data from executing RW code. So in this case, we never want to use the training data in the mrc_cache for recovery mode. 3. If !HAS_RECOVERY_MRC_CACHE && VBOOT_STARTS_IN_ROMSTAGE, this means that memory training happens before verfied boot, meaning that the mrc_cache data is generated by RO code, so it is safe to use for a recovery boot. 4. Any platform that does not use vboot should be unaffected. Additionally, we have removed the MRC_CLEAR_NORMAL_CACHE_ON_RECOVERY_RETRAIN config because the mrc_cache driver takes care of invalidating the mrc_cache data for normal mode. If the platform: 1. !HAS_RECOVERY_MRC_CACHE, always invalidate mrc_cache data 2.
